a 7.5 kg bowling ball is in front of a large, compressed spring. The spring has a constant of 500 N/m, and 225N of force was required to compress the spring. How far was the spring compressed?

The most important difference between a wedge and an inclined plane is a. their size b. their shape c. how they are used d. what they are made of

Asystem containing an ideal gas at a constant pressure of 1.22×10^5 pa gains 2140 j of heat. during the process, the internal energy of the system increases by 2320 j. what is the change in volume of the gas?

Suppose that 27 j of work is needed to stretch a spring from its natural length of 6 m to a length of 9 m. (a) how much work is needed to stretch the spring from 12 m to 14 m? j (b) how far beyond its natural length will a force of 78 n keep the spring stretched?
